Abstract

PURPOSE:To make the structure simple and the contact of a massage element to a human body soft and friendly by constituting massage action of the massage element in such a way that it can be executed by repeating expansion and contraction of an air cell being connected and brought into contact with the massage element. CONSTITUTION:Base parts 3 and 3 of arms 2 and 2 having massage elements 1 and 1 on their apex parts are rockably supported in the left and right direction on a frame at the base parts 3 and 3 as supporting points. In addition, the massage elements l and 1 are elastically energized by means of springs 9 in the left and right side wall directions of the frame widening the gap. Therefore, when a pump 8 and a valve 7 are electrically energized, the air cells 5 and 5 are expanded to narrow the gap between the massage elements 1 and 1. Then, when energizing of electricity to the pump 8 and the valve 7 is shutted down, the air cells 5 and 5 are contracted to widen the gap between the massage elements 1 and 1. It is possible thereby to make the structure simple, to make the action quiet and to make the contact of the massage element to a human body soft and friendly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massaging device in which a massaging action is performed by repeating expansion and contraction of air cells.

[0002]

2. Description of the Related Art An arm having a massaging element at its tip is cranked by an eccentric cam or the like to oscillate the arm in the left-right direction or in the up-down direction, and a massaging element at the tip of the arm makes a massage for kneading or tapping. Massage devices that can be applied are widely known without mentioning known documents.

[0003]

SUMMARY OF THE INVENTION A mechanical massaging device for swinging an arm by driving a crank such as an eccentric cam complicates the structure and forcibly operates the arm by the eccentric cam. In addition, there was a problem that the movement was awkward and the contact with the body was rigid.

[0004]

The massage device of the present invention is a massage device in which an arm having a massager at its tip is supported so as to be swingable in the left-right direction or the up-down direction with its base as a fulcrum. It is configured so that the massager is massaged by swinging the arm by repeatedly controlling the expansion and contraction of the air cell connected to the.

[0005]

When the air is sent to the air cell to expand the air cell, the distance between the massaging elements on the left and right in the massage apparatus is narrowed as shown by the one-dot chain line in FIG. 1, and on the contrary, the air in the air cell is discharged. As it is contracted, the distance between the left and right massaging elements becomes wider as shown by the solid line in FIG. Repeated massages are given.

Further, in a beating massage device which swings the arm up and down, when air is injected into the air cell to expand the air cell, the arm rotates about the base as a fulcrum, as shown by the one-dot chain line in FIG. When the massager side is pushed down and air in the air cell is discharged and contracted on the contrary, the massager is pushed up as shown by the solid line in FIG. 2, and the repeated pounding massage is performed.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, in FIG. 1 of the first embodiment, the bases 3 and 3 of arms 2 and 2 having massaging elements 1 and 1 at the tip end are attached to a frame 4. A chair type of a second embodiment, which is swingably supported in the left and right directions using the bases 3 and 3 as a fulcrum, and in which a frame is moved up and down along a guide (not shown) by a screw rod. Then, the base 3 of the arms 2 and 2 is supported by the frame 4 so as to be vertically swingable about the base as a fulcrum.

The air cell 5 is installed between the frame 4 and the arm 2 and is connected to the pump 8 via the air tube 6 and the valve 7. Reference numeral 9 denotes a spring that elastically urges the massaging element 1 in a direction of moving away from the contact with the body. With this spring 9, the massaging elements 1, 1 in FIG. Direction, and in FIG. 2, the massaging element is elastically biased toward the upper wall of the frame.

When the pump 8 and the valve 7 are energized, FIG.
As indicated by the alternate long and short dash line, the valve body 10 of the valve 7 is pulled against the spring 11 to open the air supply hole 12, and the passages 14, 14 communicating with the air cell from the pump communicate with each other.
The passage leading to the exhaust holes 13, 13 is closed, and the air cell is expanded. Therefore, in FIG. 1 of the first embodiment, the interval between the massaging elements is narrowed, and in FIG. 2 of the second embodiment, the massaging elements are pushed down.

When the power supply to the pump 8 and the valve 7 is cut off, contrary to the above, the valve body 10 is pressed and pushed down by the spring 11 as shown by the solid line in FIG. 3, and the air supply hole 12 is closed. Since the passages to the exhaust holes 13 and 13 are opened, the air cell 5 is contracted, the interval between the massaging elements is widened in FIG. 1 of the first embodiment, and FIG.
Then the massager is pushed up.

[0011]

As described above, according to the present invention, the swinging of the arm having the massaging element at the distal end is performed by repeating the expansion and contraction of the air cell. Therefore, the swinging of the arm is operated by an eccentric cam or the like. Compared to the mechanical type, the structure is simpler, the operation is quieter, and the air cell acts elastically on the arm, so that the contact of the massager with the body is soft and easy to fit.
